El Chaltén is Argentina's youngest city, placed near the Chilean border in 1985 by the government to beat its rival country to the land claim. The place still feels like a frontier town, with packs of wild dogs patrolling the streets, but in one key way it's very urban: La Cervecería. The female brewmaster here crafts two types of beer (bock and pilsner) using traditional Bohemian recipes and techniques. After hiking to nearby Laguna Torre at a grueling pace, we stopped in for celebratory brews. The bock was malty and slightly sweet—light for a bock but still a little heavy for me, post-hike—while the pilsner clearly hit the spot: light and refreshing.
